` Application tied Juiy i 3,

To all whom t may concem Be it known that I, CARL A.. ANDERSON, asubject of the King of Sweden, residing at Boston, in the countyof-Suffolk and -State of Massachusetts, have invented new andv usefulImprovements in Boomerang Throwers, of which the following is aspecification.

This invention relates to a boomerangthrowing device including `aflat-surfaced tablety adapted to support a boomerang in position to bethrown edgewise, a handle to be grasped by the operator, a springadapted to bel set for action y byv the operator, means actuated by thespring to impart a forcible edgewise movement to al boomerang supportedbyy the tablet, and a trigger adapted to. releasably confine said`springactuatedV means, and permit the same to act on the boomerang'.

The invention is embodied in the improvements hereinafter described andclaimed in a boomerang thrower characterized as above stated,`theobjects attained by said'improvements being fully set forth hereinafter.i

Of the accompanying drawings forming a- 1 part of this specication,-

Figure 1 is a side view of a boomerang thrower embodying the invention.

Figure 2 is a top plan view of the same.

Figure 3'is an enlarged fragmentary section online 3-3 of Figure 2.

Figure 4 is a top plan view, the tablet beingA removed. v

Figure 5 is a side viewA of a portion of the boomerang shown `by dottedlines in Figures 1 and 2.

Figure 6 is a view similar to Figure 5, showing a modification. l

The saine reference characters indicate the same parts in all of thefigures. l

In the drawings, 12 `represents a Hat tablet, preferably of sheet metal,secured to a holder which includes a .base portion on which the tabletis seated, bearings at one end of the base portion, and ahandle at theopposite end of` said portion. The holder is preferably formed from anelongated metal strip, bentv to form alooped` central portion 13,constituting the handle, parallel ,connected portions 14, rivetedtogether at 15 (Figure 3)` and constitutingy the base portion, and endportions 15 and 16, bent downward from the base-forming portions 14, andprovided with ears 17 and 18, which are apertured at 19 to form thebearings which are spacedl apart, as shown 1922,; serial No. 572,563.v

- by Figure 1. A rod`20 isjournaled in saidl fbearings, and is providedat its iipperend'V i with. providedat itsouter end with an upstandanangular arm 21,"bent yat 22, and,

ing finger 23. 24 represents a helicalsprinfr.

one end of which is'engaged at 25 with the end portion 16, andthe otherend at 26, with the rod 20. A movement of theA arm 21 to the Vfull linestarting position shown by Figures l, 2, and 4, compresses the spring,so that thevlatter'ten'ds to vforce the arm-to vthe dotted-'linestopping'position shown by vsaid figures. When the arm is in thestarting position, the finger 23 projects across kone endof the tablet12, and when the arm is inthe 'stopping position, the linger projectsacross the opposite endof the tablet. The arm g is releasably conned inits starting position by they trigger hereinafter described, and isarrested in its stopping position by` the end. portionl of the holder,vas shown by Figure 4.

The trigger is composed lof a` resilient strip 28, attached at29-to thehandleportion 13, and a hooked terminal 30, attached tothe free end ofthe strip andnormally f i held bythe latter agains'tuone side ofthe arm2l. handle portion 13, yand is arranged tol form a finger rest on whicha finger of the hand The strip 28 extends beside the.

grasping the handle-may be `pressed to Inove-I Y the trigger in thedirection of arrow Figl ure l), and thereby release the arm.

The tablet is-preferably secureddetachably tol the base portion oftheholder, so that lthe tablet and holder rmayxbe separated and compactlystored. Tofthis end I employl bolts 32, linserted in coinciding holes Iformed inthe tablet and in `the .base portion ofthe holder, said bolts`having heads 33,

bearing on the upper side of the tablet, and clamping wing nuts 34,engaging said bolts and bearing on the under side of the base portionofthe holder.

To prevent obstruction of the `upper surface of the tablet by the boltheads, I provide the tablet with bosses 36,forming de- Y pressedportions on which the bolt heads are seated, said heads being flushVwith vthe up.-

per surface of the tablet, as shown byFigure 3. The bosses 36 maybeprovided with slots 37, (Figure 2), arranged to .receive the` heads 33(which are` oblong), whenithe heads are turned from the position shownby Figure 2, to coincide with thek slots. Thev tablet may, therefore,bev separated from the; f

holder without removing the bolts from the latter.

The rod 20 is loosely confined by the spring 24 in its bearings, so thatit may be moved endwise when the tablet is detached. Provision is thusmade for storingl the arm 21 beside the holder in the right-hand dottedline position shown by Figure 4. To locate the arm in this position, therod 2O is first moved upwardin its bearings, until thev arm is free toswing across the holder, then swung in the direction of arrow jz/(Figure 4) across the holder, and then moved downward to cause thespring, now under relatively slight tension, to hold the arm against theholder.

40 represents a boomerang, which is a thin angular strip of any suitablematerial, such as hard rubber, vulcanized fiber, etc., adapted to lieflat on the upper surface of the tablet. In oneend portion of theboomerang is an orifice 41, adapted to loosely receive the upstandingfinger 23. When the arm 21 is confined in its starting position by thetrigger, the boomerang is deposited on the tablet, its orice 41receiving the Afinger 28. When the trigger is manipulated to release thearm 21, the linger and the boomerang are swung around to the stoppingposition of the finger. The tablet is provided with means for liftingthe boomerang from the finger when the latter reaches or approaches itsstopping position, saidmeans being preferably an inclined strip 43,arranged to force the` boomerang upward until it leaves the finger. Theboomerang is now forcibly projected from the tablet, and has an orbitalmovement, causing it to move first away from the throwing instrument,and then return to the neighborhood thereof.

I am not limited to the employment of means on thel tablet for liftingthe boomerang to disengage it from the finger 23. As shown by Figure 6,the boomerang may be provided with an open slot 42, which receives thelinger when the latter is in its starting position. When the finger isreleased by the trigger, it bears on the edge of the slot 42, andimparts a whirling edge,- wise movement to the boomerang, until the armapproaches its stopping position, the slot then permitting theseparation of the boomerang from the pin. It will be seen, therefore,that when the boomerang is provided with an opening, as the orifice 41,formed to surround the pin 23, lifting means, such as the incline 43,will be necessary, but when the opening is a slot 42, said lifting meanswill be omitted.
